FLASH CARD : HARDWARE , SOFTWARE , AND OPERATING SYSTEM OF COMPUTER

 

 

1. MONITOR 

 A monitor is an electronic device used to display video output from a computer. Screen monitors are used in many computer devices, from personal computers (PCs) and laptops to small mobile devices, such as cell phones and MP3 players.

 

2. CPU

The central processing unit (CPU) guides the computer through the various steps of solving a problem. Data enters the computer through an input unit, is processed by the central processing unit, and is then made available to the user through an output unit.

        

3. PROCESSOR

A processor is a logic circuit that responds to and processes the basic instructions that drive a computer. The processor is seen as the main and most important integrated circuit (IC) chip in a computer, as it is responsible for interpreting most of the computer's commands.

4. RAM

Random access memory (RAM) is a computer's short-term memory, which it uses to handle all active tasks and apps. None of your programs, files, games, or streams would work without RAM.

5. MOTHERBOARD

The motherboard is the backbone that ties the computer's components together at one spot and allows them to talk to each other. Without it, none of the computer pieces, such as the CPU, GPU, or hard drive, could interact. Total motherboard functionality is necessary for a computer to work well.

6. CD-ROM

CD-ROM function for used to store programs and data files, a CD-ROM holds 650MB or 700MB of data and employs a different recording format than the audio CD (CD-DA), from which it evolved. In the 1990s, the CD-ROM rapidly replaced the floppy disk for software distribution.

7. HARDDISK

Computer hard drive (or a hard disk or HDD) is one kind of technology that stores the operating system, applications, and data files such a documents, pictures and music that your computer uses. The rest of the components in your computer work together to show you the applications and files stored on your hard drive.

 

8. MOUSE

A mouse typically controls the motion of a pointer in two dimensions in a graphical user interface (GUI). The mouse turns movements of the hand backward and forward, left and right into equivalent electronic signals that in turn are used to move the pointer.

 

9.KEYBOARD

A keyboard's primary function is to act as an input device. Using a keyboard, a person can type a document, use keystroke shortcuts, access menus, play games and perform a variety of other tasks

10. FAN/HEATSINK

The computer fan is attached to the computer casing which is used to cool the processor temperature. The exhaust fan draws cold air into the case from the outside, expels warm air from the inside and moves air across the heat sink to cool certain components.

SOFTWARE

1. MICROSOFT WORD

  Microsoft Word is a word processing program that is part of the Microsoft Office Suite package. The main purpose of Word is to create text documents that can be saved electronically, printed on paper or saved as PDF files.

2.MOZILLA FIREFOX

 1. WINDOWS

Windows is an operating system has three main functions:

 (1) manage the computer's resources, such as the central processing unit, memory, disk drives, and printers,

(2) establish a user interface

(3) execute and provide services for applications software.

 

 

2. LINUX

Linux is an open source operating system (OS). An operating system is the software that directly manages a system's hardware and resources, like CPU, memory, and storage. The OS sits between applications and hardware and makes the connections between all of your software and the physical resources that do the work. 

3. MAC OS

macOS is the operating system that powers every Mac. It lets you do things you simply can't do with other computers. That's because it's designed specifically for the hardware it runs on — and vice versa. macOS comes with an entire suite of beautifully designed apps.
